Who’s in Space Right Now?

WatchSat shows a live count of the people currently in orbit aboard the world’s space stations — the International Space Station and China’s Tiangong — with each crew member named, from live data. The exact number changes with every launch and landing.

Robots exploring in our place

Beyond the crews, dozens of uncrewed spacecraft are at work across the solar system: rovers and orbiters at Mars, orbiters at the Moon, probes flying through the Sun’s corona, missions cruising to asteroids, Juno at Jupiter, and the Voyagers and New Horizons out in interstellar space and the Kuiper Belt. Each links to a live view — the stations to their trackers, the planets, Moon and Sun to the 3D globe, and the interstellar craft to Deep Space.

Crews rotate and missions come and go: the human count here is live, and the robotic roster is a maintained snapshot. Open the live globe to see it all in 3D.
